CARPET-STRETCHER.

SPECIFICATION forming part of Letters Patent No. 435,920, datedSeptember 9, 1890.

Application filed November 15, 1889- Serial No. 330 473 (No model.)

To all whom it may concern:

Be it known that I, MANSFIELD J. COOK, of Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Carpet-Stretchers, of which the following, taken inconnection with the accompanying drawings, is afull, clear, and exactdescription.

This invention relates to the class of carpet-stretchers in which thecarpet-engaging bar is movably connected to a bar provided with a spurengaging the floor, and a lever is employed to draw the carpet-engagingbar toward the aforesaid spur; and the invention consists in an improvedconstruction and combination of parts which form a carpetstretcher whichis simple and compact in construction, and convenient, efficient, anddurable in its operation.

The invention is fully illustrated in the annexed drawings, in whichFigure 1 is a side view of my improved carpet=stretcher. Fig. 2 is a topplan view of the same. Fig. 3 is a perspective view of thecarpet-engaging bar, and Fig. 4 is aninverted plan view of theratchet-bars.

Similar letters of reference indicate corresponding parts.

A represents the bar or plate which engages the carpet to be stretched.This bar I form of a wooden plate A, in the under side of which aresecured a series of pins or teeth adapted to engage the carpet. To thetop of this wooden plate is securely fastened a metal 3 5 plate A whichis preferably made to extend over the entire length and width of thewooden plate, and is formed with upwardprojecting guides at a, disposedtransversely thereon and equidistantly from the center of the length ofthe plate. Said guides are formed with overhanging lips a a, for thepurpose hereinafter explained. Said metal plate is also formed with anupward-proj ecting tooth 1), between the aforesaid guides and 5 havingan elongated engaging'face standing lengthwise of the plate or at rightangles to theline of the guides. In these guides slides a bar B, formedwith longitudinal side flanges n at, over which the aforesaid lips a aproject, and thus prevent the bar 13 from being lifted completely offfrom the plate A". There is, however, sufficient room under the saidlips to allow the bar to be lifted suffi-= ciently to release it fromthe tooth b, which it engages by ratchets 0 0, formed on the un- 5 5 derside of the bar B. The front end of the latter bar has affixed to it adownward-projecting spur c, by which it is adapted to engage the floor.The bar B is also formed with upwardly-projecting ears (Z d and with alongitudinal slot f, which is central between the ratchets 0 0, andextends between the aforesaid ears. To these ears is pivoted a lever l,to the lower end of which is connected a ratchet-bar e, which slideslongitudinally in the slot f, and is adapted to engage and release thetooth b.

The described carpetstretcher is operated by pressing the spur 0 intothe floor in advance of the edge of the carpet to be stretched, and thebar A is slipped back on the bar B and placed upon the carpet. Thenbythrowing the lever l forward the ratchet-bar e is pushed rearward, andin swinging the lever rearward the said ratchet-bar engages the tooth band draws thereby the bar B forward, and the latter draws with it theunderlying carpet. If it is necessary to further stretch the carpet, thelever Z has to be again thrown forward to carry the ratchet-bar 6 backto ob- 8o tain a new hold on the tooth 1). During this movement theratchets 0 0 of the bar B engage the tooth b, and thereby retain thecarpet-engaging bar A in position.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-= 1. A carpet-stretcher composed of acarpet-engaging bar, a ratchet-bar mounted movably longitudinally on theaforesaid bar and 0 adapted to engage and release the same and providedat its front end with a spur adapted to engage the floor, a leverpivoted to said ratchet-bar, and a ratchet-bar connected to said leverand adapted to engage and release 5 the carpet-engaging bar,substantially as set forth and shown.

2. The combination of the carpetengaging bar A,provided with the guides01. a and tooth b, the ratchet-bar B, slidinglongitudinally in too sitesides of the slot, the lever Z, inserted between said ears and pivotedthereto,and the ratchet-bar e, sliding in the slot f and connected tothe lever, substantially as described and shown.

In testimony whereof I have hereunto signed my namet-his 12th day ofNovember, 1889.
